I am using the latest version of Firefox with Mojave on a Mac.

Lately I have experienced slowness despite the fact that I didn't add any software and I have Norton checking for viruses. Recently I got a message "Your system has run out of application memory" when I had 5 tabs open in Firefox. I checked Activity Monitor and it showed Firefox using 1.16 GB. 7 other apps were open, the next one with the highest memory usage was Mail (465 MB). Activity Monitor showed 30 instances of FirefoxCP Isolated Web Content entries.

I attached a screen capture showing what Firefox was using in one of these instances. Is this "normal" with 5 tabs open?

I closed the open tabs and quit Firefox. Memory usage by Firefox went down, but after a short time the problem happened again.

A search on the internet showed lots of similar complaints about FirefoxCP Isolated Web Content. Is this a known bug? Any way to avoid this problem?

Thanks.
